In Shanghai the American missionaries dominated Chinese education, such as it was. I was surprised to find families of eight or ten children the rule rather than the exception among them. Their salaries were raised with each new infant, and that may have been the reason. Nevertheless, there were many who wanted birth control information. When they learned of my presence they called on the telephone, sent cards, came to see me. But, apparently apprehensive of criticism, they took me if possible into a secluded room or, if we had to meet in a public place, backed me into a corner and stood in front to conceal the fact they were talking with me; they acted as though they were turning up their coat collars so that they should not be recognized. The only method of family limitation known to the poor Chinese was infanticide of girl babies by suffocation or drowning. The missionaries were co-operating with the Government, which had enacted a law forbidding the practice. They went from home to home to see whether any woman were pregnant. If one were obviously so, her name was jotted down in a notebook for a call soon after birth was due. At the same time both father and mother were informed of the severe penalty they would incur unless the baby itself or a doctor’s certificate of death from natural causes were produced. After two years’ work ninety-five percent of pregnant mothers showed either their babies or good reasons for not doing so. But the Chinese had so low a margin of subsistence that, if the law forbade them to dispose of one child, another was starved out. Sometimes two little girls had to be sold to keep one boy alive; in dire necessity even he might have to be parted with to some sonless man who wanted to ensure ancestor worship. Because the elder girls could begin to help in the fields or become servants in some rich landowner’s household, usually it was the three- and four-year-olds who were turned over to brothels. There they stayed until mature enough to be set to working out their indenture. If they ever tried unsuccessfully to find freedom, the proprietors might beat them unmercifully, sometimes even breaking their legs so that they could not walk, much less ever run away again. When infanticide was stopped, the corresponding increase in sing-song girls making their living by prostitution was almost immediately evident. It was estimated Shanghai had a hundred thousand. Many were Eurasians, the results of unions with white men who were in Shanghai on small salaries as representatives of foreign business firms. I glimpsed some of the Chinese women who had been bought as housekeepers and mistresses as well saying good-by at the train to their American or English masters summoned home.
